Stratified soils particularly those soils with variable or contrasting textures in contrast to homogenized depositions; soil moisture characteristics including AWC, infiltration, subsoil permeability etc.
If you are interested on the patterns that soil water content has on a multi-layered soil type, the main issue is that the fluctuations of water content over depth are larger than in a homogeneous soil type. It is expected that the deeper it goes, the less variability on soil moisture is identified. However, for multi-layered soil types, it is possible to identify, in some cases, the differences in porosity as well the specific surface area may either increase or decrease the water content over time during or after rainfall/irrigation events.
In case of irrigation, try to check the initial and after irrigation soil moisture for a particular area.
They are inpredictable in terms of FC, texture and porosity in the scale of a field. Soil survey requires to be made in a larger scale.
When the root zone depth is higher than the lateral groundwater level in the vicinity adjacent to river, no problem exaggerates to plant health.
Yes when the full depth of the root zone is higher than the lateral groundwater, plant enjoys a good and healthy condition. Usually one see a high density plant along natural rivers and streams. Also good water quality aids to grow plant rapidly.
